Brane Inflation and the Overshoot Problem
Simeon Bird, Hiranya V. Peiris, Daniel Baumann
We investigate recent claims that brane inflation solves the overshoot problem through a combination of microphysical restrictions on the phase space of initial conditions and the…
Holographic Systematics of D-brane Inflation
Daniel Baumann, Anatoly Dymarsky, Shamit Kachru +2
We provide a systematic treatment of possible corrections to the inflaton potential for D-brane inflation in the warped deformed conifold. We consider the D3-brane potential in the…
A Microscopic Limit on Gravitational Waves from D-brane Inflation
Daniel Baumann, Liam McAllister
We derive a microscopic bound on the maximal field variation of the inflaton during warped D-brane inflation. By a result of Lyth, this implies an upper limit on the amount of grav…
